Parasound JC2 pre a good match for Pass X150.5 ?

I would not worry about getting the 250.5 over the 150.5, you will never even come close to driving the 150.5 to even half-way. The allure of extra power from the 250.5 is purely psychological. Re the JC-2, I have had problems in past with hum issues when connected to other brands (Not specifically with JC-2 but Halo gear in general). Even called Parasound for help and despite experimenting with "cheater plugs" etc, it did not resolve (the amp in that case was the A21). Just my experience...others may have different feelings

Thanks Upgrade. I am not so sure at the minute that the Pass X150.5 will be up to the task of driving the Maggies like I am sure the 250 would, hopefully it will be ok. Should be up and running within a week.

Thomas, I occasionaly run low power tubes with my MMG's. No problem. I can't see you not enjoying the 105.5 with the 1.6's.
